Thanks! That was it. I had been working on removing the video unit. I put it back in and yanked the drivers unit. Now it works. (Although I'm not sure if the program actually does use CGA graphics in another part of the program--in case it does, I'd appreciate any ideas people would have.)
Thanks again, Tomas!

Yes - it's specifically Crt plus Drivers (which in turn uses Keyboard
and Mouse units), which interfere. Crt should be rewritten to use
unit Keyboard for ReadKey and KeyPressed implementation - this should
probably resolve most of the problems. The other part (Crt accessing
console independently of the Video unit) isn't good design, but
shouldn't be causing your problems.
